Finally a Blue Pill that is perfect. These new boards came with the correct USB pull-up resistor of 1500 ohms instead of the wrong one of 10000 ohms as documented all over the web. AND, a bonus, a blink sketch already loaded. Plugged it in and it was ready to go.

Excellent value for money with these boards, but be aware they use the CKS CS32F103C8T6 unlicensed Chinese clone of the STM32F103, and there are some subtle differences. The data sheet, and a discussion about this part can be found in an EEVblog thread (use Google search). It connected to my STlink OK, registered as an STM103 and I downloaded a Forth programming environment into it, one of the more complex programs I have for this CPU. It worked fine. I couldn't see any problems. In any case, I change the CPU on many of my Blue-pills to STM32F303CC :)

Bang for the buck can not be over stated. Be aware that the boot loader is NOT on the card when it comes. You need a USB serial cable. Follow the online instructions on line -- search for blue pill then kill your project with cheap computing power

Its a step up from other similarly sized MCU boards, because it has a 32 bit processor and flexibility that seems like quite a good deal.

This is a very nice basic board providing access to all MCU pins, and includes two crystals and a voltage regulator. All for a price well below what any of us can buy just the MCU chip itself for! It's lower in price than you can typically find an Arduino Nano for, and is about 10x better in just about any way you can measure it. Lots of development platforms and tools available for it, as well as a huge amount of online support. I can't recommend it more!
